I think I found what you are looking for. It will not let you view it
directly, but it will let you convert it to html. It is called nse2html.
Since it is only 2k, I have attached a gzipped version. It seems that it
is in perl so I think just running it will work.
My source was

If you have any other question email me - not just the mailing list.
